ROOM HUMIDIFIER Filed Nov. 25, 1949 INVENTORS Patented June 12, 1951 ROOM HUMIDIFIER Abrom L. Feldman and Ira Schneid, Atlanta, Ga., assignors to Puritan Sales Company, Atlanta,

Application November 25, 1949, Serial No. 129,389

1 Claim. 1

This invention relates to room humidifiers.

An object of this invention is to provide a humidifier for mounting in a convenient location in a room so that humidity of the room may be maintained.

Another object of this invention is to provide a room humidifier which embodies a receptacle for holding water and one or more clay bodies seated in the receptacle, and projecting thereabove, the clay bodies being kept moist by capillary attraction and the moisture evaporating in the air.

A further object of this invention is to provide clay or moisture absorbing bodies adapted to be mounted in a receptacle, the bodies being hollow and formed with fluted or grooved outer surfaces for increasing the surface contact with air so as to increase the evaporation of moisture.

With the above and other objects in view, our invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawing,

Figure 1 is a detail side elevation, partly broken away and in section, of a humidifier constructed according to an embodiment of this invention,

Figure 2 is an end elevation of the device,

Figure 3 is a sectional view taken on the line 33 of Figure 1.

Referring to the drawing, the numeral I designates generally a receptable which is adapted to hold water and is formed with an open upper portion I I. The receptacle I0 includes a bottom wall I2, opposite side walls I3, and opposite end walls I4. The side and end walls are curved inwardly, as indicated at I5, and as shown in Figures 1 and 3, the side and end walls are disposed in upwardly convergent relation.

A moisture absorbing and conducting or evaporating member generally designated as I6 is disposed within the receptacle Ill and projects for a substantial distance above the top of the receptacle. The moisture absorbing member I6 is formed of a pair of upwardly convergent side walls I! and opposite vertically disposed end walls I8. A base flange I9 is formed at the lower end of the absorbing member I6, and preferably a plurality of openings or slots 20 are formed in the lower end of the absorbing member I6 so that water within the receptacle I0 may freely enter the interior of the open lower end of the absorbing member IS.

The absorbing member I6 is preferably formed of clay or the like, which under capillary attraction will be moist throughout the projecting portion thereof which is disposed above the receptacle I0.

In order to provide increased air contacting surface on the outer sides I! of the absorbing member IS. the outer sides I! are formed with vertically disposed channels or flutings H. The top wall 22 of the absorbing member I6 is formed with an opening 23 and the end walls I8 are also formed with openings 24 which are disposed slightly above the top of the receptacle ID. The provision of the openings 23 and 24 assures the contact of air with the inner and outer surfaces of the absorbing member I6 so that the moisture carried by the member I6 will readily evaporate into the air.

In the use of this device. the receptacle I I] is herein shown as being of a length sufiicient to hold two of the absorbing and moisture evaporating members I6. When water is placed in the receptacle I0, the absorbing members I 6 will be moist throughout the projecting portions thereof above the receptacle In so that the moisture will readily evaporate into the air and by providing the openings 23 and 24, the air can freely circulate within the interior of each absorbing member It.

The receptacle I0 may be formed out of any suitable material which is of Waterproof construction and in order to make the device somewhat attractive, ivy or the like may be placed within the receptacle II] on opposite sides of the absorbing member I6. I

We do not mean to confine ourselves to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What we claim is:

A room humidifier comprising a receptacle adapted to hold. water, and a hollow water absorbing member disposed in said receptacle and projecting thereabove, said member being formed of upwardly converging fluted side walls, a top wall and opposite end walls, and a plurality of apertures formed in said walls disposed above said receptacle for conducting air upwardly into and out of said member.
